[Prostate cancer in elderly subjects: how diagnosis should be made, why and how geriatric assessment should be implemented]

Managing an elderly subject with prostate cancer brings into play the notion of likelihood of survival before any diagnostic or therapeutic decision can be made. The diagnostic strategy must be specified for each patient in accordance with the clinical presentation so as to determine whether prostate biopsies are indicated in this elderly population. To estimate the likelihood of survival, one must make use of geriatric assessment techniques comprising medical strategies ranging from screening for frailty to detailed geriatric evaluation for the most complex patients. The many tools available for estimating the likelihood of survival requires a critical review of their advantages and disadvantages in daily clinical practice.
